CHARLES L. GARDINER, OF BINGHAMTON, NEW YORK, ASSIGNOR TO THE 1900 WASHER COMPANY, OF BINGHAMTON, NEW YORK.

WATER-FILTER.

To all whom it may concern:

Be it known that 1, CHARLES L. GARDINER, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented a new and useful Water-Filter, of which the following is a specification.

This invention relates to water filters and more particularly to a cleaning device for automatically removing any deposits of mud, slime and the like from the surface of the filtering medium.

The object of the invention is to provide a cleaning device in which the abrading member is automatically moved in contact with the filter stone as the latter is revolved by the action of the water, thus polishing the exterior surface of the stone and maintaining the latter in a clean sanitary condition.

A further object of the invention is to pro vide a guide ring or member operatively connected with the swing gate of the abrading member, said guide ring serving to insure a firm contact of the abrading member against the filter stone as the latter revolves and also serving to center the parts and prevent rattling or wabbling of the same.

A further object is to provide means for limiting the swinging movement of the abrading member so as to prevent the filter stone from being reduced .in size beyond a predetermined cross sectional diameter by the action of said abrading member.

A still further object of the invention is generally to im rove this class of devices so as to increase t ieir utility, durability and efficiency.

Further objects and advantages will apear in the following description, it being un- Eerstood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the ap ended claims.

11 the accompanying drawings forming a part of this specification: Figure 1 is a longitudinal sectional view of a water filter constructed in accordance with my invention. Fig. 2 is a top plan view of the same with the cover and Water wheel removed showing the cleaning element in normal or inoperative position. Fig. 3 is a similar view showing the position assumed by the cleaning element when the filter stone is revolved. Fig. 4 is a perspective view of the swing gate detached.

! Fig. 5 is a perspective view of the guide ring detached. Fig. 6 is a similar view of the segmental operating lever detached. Fig. 7 is a detail front elevation of a portion of the intorior of the casing showing the stop lug of the guide ring. Fig. 8 is a vertical sectional view taken on the line 88 of Fig. 7.

Similar numerals of reference indicate corresponding parts in all the figures of the drawin s.

The flltor comprises a casing or housing 5 having its u per portion off set to form an annular shou der 6 and thence extended laterally to produce a circumferential flange 7, which latter forms a support for the top plate or cover 8.

The top plate 8 is provided with a ni ple 9, the interior walls of which are threat ed for connection with a hydrant or other suitable source of water supply, said cover being rovided with a depending flange 10 wl iich overlaps the flange 7 of the casing and is secured thereto by bolts or similar fastening devices 11.

Arranged beneath the top or cover 8 is a diaphragm 12 preferably curved to conform to the shape of the cover and spaced from the latter to form an intermediate chamber or compartment 13 adapted to receive the water from the hydrant or other source of supply.

The diaphragm 12 is provided with a marginal flange 14, which latter is interposed between the flanges 10 and 7 and 1s spaced from the same by suitable washers or gaskets 15.

Depending from the central portion of the diaphragm 12 is a lug 16 having a socket 17 formed therein and constituting a bearin for the upper end of a vertically disposed shaft 18.

Secured to and mounted for rotation with the shaft 18 is a porous filter stone 19 preferably cylindrical in shape and provided with an interior bore, spaced from the shaft, to form an intermediate water receiving chamber 20, there being a longitudinal opening 21 formed in the lower end of the shaft 18 and communicating with the chamber 20 by means of apertures 22, thereby to permit the discharge of the filtered water.

The upper end of the shaft 18 is threaded at 23 for engagement with a clamping nut 24, which latter bears against a plate or washer 25 carried by the upper end of the filter stone.

Disposed in spaced relation to the plate 25 is a circular plate or disk 26 having its lower face provided with a lurality of radiating blades or pockets 27, W ich latter receive the impact of a stream of water issuing from suitable discharge nozzles 28 clependin from the diaphragm 12, there being suitab le depressions 29 formed in theup er surface of the diaphragm at each depenc ing nozzle 28 so as to permit the ready flow of water from the chamber 13 through said nozzles to the blades of the water wheel. The circular plate 26 of the water wheel is provided with a centrally disposed opening the interior walls of which are threaded for engagement with the threads on the shaft 18 whereby rotary movement imparted to the water wheel will efiect a corresponding rotary movement of the filter stone.

The cleaning element forming the subject matter of the present invention comprises a swing gate or holder 30 having spaced lugs 31 extending laterally from one longitudinal edge thereof and connected by a rod or pin 32, which latter, is pivotally mounted in corresponding lugs 33 secured to or formed integral with the interior wall of the casing 5, as best shown in Figs. 1 and 7 of the drawing. The swinging gate or holder is provided with a vertically disposed seating groove 34 for the reception of an abrading element 35, the latter being preferably inthe form of a stick of carborundum or the like. The abrading member 35 is clamped in position on the swinging gate or holder by means of a plate 36 having transverse slots 37 formed therein for the reception of screws or similar fastening devices 38, there being a strip of rubber or other yieldable material 39 interposed between the abrading stick 35 and the adjacent wall of the slot 34 in order to form ayieldable seat for said abradingmember. Extending laterally from the opposite longitudinal edge of the swinging gate or holder 30 are spaced arms 40 and 41, which latter are curved to conform to, and normally bear against, the interior walls of the casing 5.

Slidably mounted on the annular shoulder 6 is a guide member or ring 42 having spaced fingers 43 extendinglaterally from the inner face thereof and forming between them an elongated slot 44 adapted to receive the adj acent end of the pivot pin 45 of a segmental actuating lever 46. One end of the actuating lever 46 is provided with a vertically disposed stud 47, which enters the recess 43 of a hook 49 carried by and extending in a horizontal plane from the ring, as shown. The opposite end of the segmental lever 46 is provided with a depending sleeve 50 adapted to receive the angular extension 51 of a connecting rod or link 52. The lower end of the ated power transmission member or disk 54 provided with a peripheral flange 55 having an opening 56 formed therein for the reception of the angular extension 57 of the connecting rod 52 sot'hat when the filter stone 19 is rotated by the water wheel the disk or attaching member 54 will also be rotated and through the medium of thelever 46, rod 52 and guide member 42 actuate the abrading member to effect the cleaning of the filter stone.

As a means for limiting the inward movement of the swinging gate there is provided a stop lug 58 which depends from the inner edge of the guide ring 42 and is disposed in the path of movement of the adjacent lug 33 so that when the filter stone is cut or worn away until the cross sectional diameter of the stone isof the same diameter as ti body of the disk 54, the lug 58 will engage the lug 33 and thereby render the abrading element inactive.

In operation water is admitted to the chamber 13 through the nipple 9 and is spread over the surface of the diaphragm 12 in the form of a thin film, the liquid from the chamber 13 passing through the discharge nozzles 28 and being directed against the blades 27 of the water wheel thereby to rotate the same. As the filter stone 19 re volves the disk 54 by frictional contact therewith, will be partially revolved thus exerting a pull on the connecting rod 52 and through the medium of the segmental lever 46 and guide ring 42 move the swinging gate on its pivot 32 inwardly until the abrading strip 35 bears against the exterior face of the filter stone. As the filter stone wears away the swinging gate will be automatically forced inwardly so as to maintain the strip 35 in constant contact with the filter stone. When the diameter of the filter stone is approximately the same as the diameter of the body portion of the disk 54, the lug 58 will engage the lug 33 and prevent further inward movement of the swinging frame, in the manner before stated.

Attention is here called to the fact that the guide member or ring 42 is slidably mounted on the shoulder 6 and not only-serves to insure a firm contact of the abrading stick or element against the filter stone as the latter revolves, but also serves to center the parts and prevent rattling or wabbling movement of the same.

It will of course be understood that the water will percolate through the filter stone into the chamber 20 and thence into the tube 21 where it may be drawn olf if desired through a suitable cock or turning plug provided for this purpose.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.
